On a certain map, 1 inch represents 5 miles. If the actual distance between two
towns is 136 kilometers, what is the distance between these two towns on the
map?

Is the Ans: 17 inches ?

Thanks.

1 km=0.62m
136 km=136*0.62=84.32miles

5 miles = 1 inch
84.32miles =x

x=84.32/5=16.86â‰ˆ17

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score.

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
